Frequently Asked Questions About HVAC & Plumbing Service
What services does S&D Mechanical offer?
We provide full-service heating, cooling and plumbing for both residential and commercial clients.
Do you offer emergency repair?
Yes — we provide 24-hour service for urgent heating, cooling, and plumbing issues.
How often should I schedule system maintenance?
We recommend servicing your HVAC system twice per year — once before cooling season and once before heating season.
Do you work with commercial facilities?
Absolutely. We perform full HVAC, Sewer or Water Service installations, maintenance programs, and repairs for buildings of all sizes.
Are you licensed to work in Delaware as well as Pennsylvania?
Yes. S&D Mechanical holds active contractor licenses in both Pennsylvania and Delaware, and we regularly serve homeowners and commercial clients in New Castle County, DE.
How do I know if I need a plumbing repair or a full replacement?
It depends on the age of the system, the scope of the problem, and the cost of repair relative to replacement. Our plumbers will give you a straight assessment — we'll tell you honestly whether a repair makes sense or whether you're better off replacing, and we won't push you toward the more expensive option if it isn't warranted.
Do you work on commercial plumbing and HVAC systems?
Yes. We have extensive experience with commercial mechanical systems — including office buildings, multi-family properties, retail spaces, restaurants, and high-rise buildings. We also partner with general contractors on new construction projects.
What's the service area for emergency calls?
Our emergency service covers our full service area — Delaware County, Chester County, Montgomery County, and New Castle County, DE. For urgent plumbing or HVAC failures, call (610) 485-4173 any time.
How long does a typical HVAC tune-up take?
A standard seasonal tune-up typically takes 45 minutes to an hour and a half depending on the system and its condition. We'll give you a heads-up if we find anything that needs additional attention.
Can you handle both the plumbing and HVAC work on a renovation or new build?
Yes — that's actually one of our strongest advantages. Because we're licensed in both plumbing and HVAC, we can function as a single mechanical contractor for renovation and new construction projects. It simplifies coordination and eliminates the handoff problems that come with using separate contractors.
